title: [Prevalence of known diabetes mellitus and unknown diabetes in adults from Castilla-La Mancha, Spain].
abstract: OBJECTIVE
  To estimate the prevalence of known diabetes mellitus (KD), unknown diabetes (UD), and carbohydrate metabolism disturbances in a population of Castilla-La Mancha (CLM) older than 30 years old; To study the cardiovascular risk factors related with diabetes.
  
  
  METHODS
  A transversal study was performed in order to determine these prevalence data. Reference date: 2007/06/01. 3,092 subjects were selected, and 1,181 of them (38.1%) participated in the study. A questionnaire, physical exploration and glucose tolerance test were performed. The diagnostic criteria of diabetes were those established by the American Association of Diabetes (ADA) and were compared with the World Health Organization criteria (WHO).
  
  
  RESULTS
  Prevalence of diabetes in individuals younger than 30 years: 17.9% (DM 10.7%, DO 7.2%). Ratio UD/KD: 0.7. Prevalence of impaired glucose tolerance (IGT) 5.6% and impaired fasting glucose (IFG) 22.3% based on ADA criteria and 7.2% if WHO criteria applied. KD, IFT and IFG increased with age. Global prevalence was higher in males (20.9%) than females (14.5%), but the prevalence was higher in females older than 74 years. A positive relationship was found with obesity, male sex, age and familiar history of diabetes.
  
  
  CONCLUSIONS
  Prevalence of diabetes in the adult population of CLM is very high, higher in males and increase with age. A great percentage of diabetic people or with carbohydrate metabolism alterations do not know that condition. This situation makes necessary to create early detection strategies.
